Finally, an easy question! The AVRS server would normally expect an
ACK back from a message that it had sent, but could also look for other
responses e.g. [AA] from UI-View (if it had "auto answer" enabled)
instead of :ackxx like in a normal ACK. It would just stop sending the
message when it either saw an ACK coming back, or one of several
"non-ACK" responses like [AA] or just stop after sending it after
several tries while getting no response at all.
